MACHINE FDR GONSTRUGTING A LAMINATED COHESIVE INTERNVOUND FABRIC BAND.

I Application filed December 13, 1920. Serial 1%. 430,444.

To all whom it may concern:

Be it known that I, LAWRENCE A. SUBEns,

a citizen of the United States, and a resident of Lakewood, county of Cuy'ahoga, and State of Ohio, have invented a new and useful Improvement in Machines for Constructing a Laminated Cohesive .lnterwound Fabric Band, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish .itfrom other inventions.

The present invention relates to an improved apparatus :t'or constructing various.

sizes of laminated cohesive interwound fabric bands'from series or" groups of closev lying parallel threads or yarns. The present machine is similar in general operation to those shown in my issued United States 1 Letters Patents Nos. 1,189,751, dated July and 1,223,636, dated April 2 1, 1917, but in the-machines of these patents no provision was made for adjusting'the distance on the tubular mandrel from the point at which the series of groups of close lying parallel yarns or threads were interwound thereabout to the rubber box in which the yarns were coated with liquid rubber or other desired adhesive material.

Long series of experiments with the types of machines mentioned and improved modi fications thereof showed that a tubular man drel of rectangular cross section seemed to.

offer less resistance to the passage of the yarns thereover, and that it was necessary to have more than half a turn around the mandrel of the yarns in a dry state, before treating with liquid rubber or other adhesive in an enclosed rubber container, in order that practically no displacement of the yarns in relation to their angle of: winding should take place.

It was also found that the crossing points of the series of groups of yarns upon the mandrel were not thoroughly coated with adhesiveunless these crossing points were changed while 111 the rubber container, and

the passage of these yarns or threads over' a certain angular incline on the mandrel to a predetermined greater width and a similar angular decline to the prevlous normal -width accomplishes this displacement and replacement without afiecting their prede termined position the band. V

A small angle of winding, as from two to five degrees to the longitudinal axis of the mandrel, has been found the most advantageous, since it gives the least amount of stretch in the finished band when under strain, and practically the maximum amount of production, and as it is seems to be the least angle at which practically no dis lacement of the yarns or threads occur. wing to the retention of practically the same angle of winding, the distance necessary for a half wrap around the mandrel varies with different width of mandrels being practically twice the distance for a 1" width mandrel as a width mandrel. Consequently, it is advisable in making different width of bands to be able to vary the distance from the position of winding of the yarns or threads to the rubber box and in the machine herein after described this is accomplished by description set forth in detail certain mecha-,

nism embodying the invention, such disclosed means constituting, however, but one of various mechanical forms in which the principle 01. the invention may be used.

In said annexed drawings Fig. 1 is a plan view of the machine Fig. 2 I

v mounting the reel standards on a sliding 4:, 1916, 1,201,774, dated October 17, 1916,

is a side view of the machine; Fig. .3 is a" sectional view on line a a Fig. 2; Fig. 4: is

a partial sectional view of the sliding gear .mounting of the power shaft in the reel standard; Fig. '5 shows a plan view of a narrow mandrel. with the yarn cages in section and a portion of'the rubber box; Fig. 6 showsfa plan view of a wider mandrel and theincreased length required from the yarn cage to the rubber box over that'shown for the mandrel in Fig. 5; Fig, 7 is a continuation of Fig. 6 showing the mandrel extended through the rubber box and with the yarns removed.

The present machine which is of the same general type as those shown in my previously mentioned patents, is provided with a suitable frame A in which is mounted a motor A, ,or other power I source, and

a power shaft A, the motor being operatively connected to the shaft by means of a belt A or in any other suitable manner.

The interwinding mechanism consists of a series of concentric tubes B B, B and B, to which, respectively, are rigidly secured the reels B, B B and B The tubes are supported by bearing rings 'mounted therebetween and each tube and bearing ring is provided with four longitudinal channels serving as guides to the groups of yarns or threads Y from the spools S carried'by each reel. At the inner ends of the tubes B B, B and B are respectively attached yarn cages B, B B and B which serve to guide the four groups of yarns or threads onto a madrel C, suitably mounted in the frame and alinged with the axis of said tubes.

Thus far the construction 'is similar in general features to the machines of mypreviously mentioned. patents, in which similar yarn cages are employed to wind the threads or yarns. and these reels are rotated simultaneously by means of suitable driving mechanism to be described in detail hereinafter. It will be clear from the patents mentioned that reels B and B are to rotate in one direction and reels B and B in the opposite direction, but at the same speed so that the four yarn groups: from each reel willbe wound upon the mandrel'in the necessary spaced relation. Thus the groups of yarns from reel B are wound in spaced rela tion on the mandrel and those of reel B over them but in the opposite direction but equally spaced, while the groups'from reel B are wound over those of reels B and B but in the same direction and "between the spaces of the groups from reel B and the groups from reel B in the same direction but between the spaces of the groups from reel I5 The whole number of groups of yarns are drawn lengthwise along the mandrel the reels rotate. the relative speeds of the two actions determining the angle of winding.

In the base A of the machine is guideway A on which is slidably mounted a subbase or plate A, the gibs A" being employed' to retain the plate "in the base. lt'lounted on this plate or sub-base A?" are standards or uprights A end A spaced apart. the end standard A having a threaded bushing or nut- A which has threaded engagement with worm screw A which rotata'bly mounted in a suitable bushing A of the'base. the worm screw having a handle and crank A by which it may be rotated to move the plate or subbase longitudinally of the machine.

These two uprights carry the four reels and the concentric tubes being provided with upper bearing portions for the tubes.

- The reels are suitablym'ounted' on the tubes ueamsoe which are rotatably mounted in the standards, the reel B having a bevel gear A attached thereto, a similar bevel gear A being attached to the reel 13 these two bevel gears meshing with another bevel gear A which is'mounted on a vertical shaft A carried by the standard. The reels B and B are similarly driven through bevel gears r 19 and A driven from the bevel gear A mounted 011 the shaft A carried by standard A To drive these shafts A and A, a longitudinal shaft A is mounted in suitable bearings A on the-standards this shaft having a driving gear A meshing with a gear A carried by thestandard. which is mounted on a short shaft A carrying another gear in mesh with a gear A slidably mounted on the drive shaft A of the machine a long key way A and key A being employed to allow such movement. The standard A has a suitable hearing A which slidably receives the shaft A the gear A being mounted in such standard so as to move therewith.

In front of the yarn cages is the mandrel C which passes through a rubber box D suitably mounted and having rubber supplying mechanism D the mandrel extending through the rubber box. The dry yearns in their interwound state pass along the mandrel. through the rubber box D where they are treated with liquid rubber or other adhesive and thence to a. series of pulling and drying rolls E mounted at the end of the machine.

In Figures 5 and 6 are shown narrow and wide mandrels C and the proportionate length from the yarn cages B to the rubber box I) required for the same angle of interwinding. The yarns or threads are wound on the spools in close lying parallel groups Y and in order that these yarns retain-their position when wound upon the mandrel C and treated with rubber in the rubber cup D, and not roll on themselves and rope up it was found necessary that they should have slightly more than half a turn around the mandrel illustrated.

When using a wide mandrel the reel standards and reels are moved backward by moving the sliding base A thus giving a greater length of mandrel. upon which the groups of yarns or threads are wound, and when narrow mandrel is used the reels are moved forward, so that in all cases at east half wrap around the mandrel is obtained before the yarns or threads are treated'with rubber or other adhesive.

In Fig. 7. which is a continuation of Fig. 6. is shown the mandrel. and its angularly increasing and decreasing width by which the yarn groups in passing thereover are exposed to the action of the liquid rubber in the rubber box. change their crossing points Y of interWind-ing and againresume these crossing points, thereby coating these normally covered points with rubber or other adhesive substance. This angle of inclination C of the mandrel to its greater width and corresponding declination C to its former normal width is determined by the width of mandrel employed, and the angle of inter-winding. When making a Wider hand, using a wider mandrel, changing also the pointof winding accordingly, it is necessary to use spools of threads having more yarns or threads wound in a group thereon or in terms of the trade more ends up in order to have the yarns or threads cover the mandrel, since the number of spools remain the same on each reel.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the fol lowing claims or the equivalent of such stated means be employed.
